Good Job, Jim! When I did the same, the bearing whine made it clear they are done. Changing out the bearings themselves is not hard. You need a 3-jaw gear-puller, but a 6" chunk of 3/4 steel pipe is a perfect installation tool. I ran into all my problems with bolts seized up in the motor bell...Bi-metalism welds them together and bolts sheared. Now have a new pump and this one is a "project".
